Process for making higher olefins

Tue, 18 Aug 2009 23:14:23 -0700

A process is disclosed for making higher olefins by oligomerization of a lower olefin e.g ethylene, to higher olefins, using catalytic distillation conditions. Simultaneously and interdependently, the lower olefin is catalytically oligomerized to higher olefins, and said higher olefins are separated and recovered as liquid....
